Okay, so I know what an Elmo/Document camera is, but my question is other brands are there besides an ELMO? I would like to be able to by one with my school sponsor money, but I don't just want to buy a cheap one. Does anyone have one? How much did yours cost? All I want to be able to do is have it act like an overhead projector without having to have the transparencies. Does this even make sense what I am asking?
